Fish or Shrimp Tacos on the Grill

Once a year DH and I head down to Los Cabos and absolutely love the fish and shrimp tacos made off the grill down there. Every time I come across a recipe for them however, they are the battered and fried version. What I'm looking for most likely consists of a simple marinade, some wonderful crema and good fresh guacamole. Can anyone help me out here? Thanks much!

What item do you need help on? The guac, the marinade, crema or fish? All of the above?

Pretty simple stuff. You can grill a sturdy fish like mahi or grouper. Softer fishes work but may be a problem for some people without a fish grill basket. Do you like a citrus marinade or tomato based marinade. In the Yucatan a puree of peppers might be used which would include habaneros. I keep my guac simple, A couple of hass avocados, some diced red onion, cilantro, jalapeno, lime juice, salt and pepper. A dash of olive oil to give it some shine. For fish tacos I would also include shredded cabbage and thin slices of radish as a topping if you want some crunch. You can buy crema at the supermarket.

For shrimp tacos I just dust them with chili powder and cumin, skewer and grill. Squeeze a bit of lime on while they cook. Again with fish I keep the flavors simple - ground chiles, a squeeze of lime or lemon, salt & pepper. Then I usually make a salsa of some sort, lettuce and radishes.

I've been using this recipe from Bon Appetit, although I cheat and used jarred salsa verde (La Victoria chunky medium) rather than make it from scratch. Also, after the first time, I stopped making the lime mayonnaise as we just weren't using it.

For a more simple version, like they make in Baja, I would marinate the shrimp in oil, garlic, lemon or lime juice, salt and freshly ground pepper for an hour or so, and then put them on a skewer and grill them.

You can buy mexican crema at any Mexican grocer. For the guac, I make mine with a little bit of garlic, cilantro, white onion (diced finely), sometimes a chopped tomato, lime juice and salt and pepper. You also will want to serve shredded cabbage and a pico de gallo salsa with the tacos.

Guac I can do with no problem. I was hoping for some fish suggestions, marinades and any other accompaniments I might have been missing. Ideally, I was looking for a very simple olive oil, lemon/lime juice marinade that would let the good quality of whatever fish I had chosen come through.

Masha, I had checked out that BA recipe and it looked pretty good to me. Glad you liked it as well!
